I have 2 sentences. Can you help me figure out what the subject, verb, object are of these sentences and why? What does each word do in these sentences? Thanks! It has been a while...

All they ever talk about is work.

All she ever does is hang out with her co-workers.

My first thoughts were

For the first sentence"work" is the subject "is" is the verb and "all they ever talk about" is an adverbial phrase

for the second sentence"hanging out with her co-workers" is the subject "is" is the verb "all she ever does" is the adverbial phrase

Then I was told

for the first sentence"they" is the subject "talk" is the verb "work" is the object "all" and "ever" are adverbs describing "talk"

For the second sentence "She" is the subject "Does" is the verb "Hang out" is the object

Then I was told that In the first sentence "all" is the subject, "is" is the verb, "work" is the predicate. "[that] they ever talk about" is a relative clause modifying "all". The second sentence has a similar structure, and "hang out with her coworkers" is the predicate. There are no direct objects in the primary structures of these sentences.

So I'm not sure

For the second sentence "She" is the subject"Does" is the verb"Hang out" is the object
